Do you have an error message or nothing at all ?
If you create a mail in your SMS Inbox in Thunderbird and then launch the synchronization, is it synchronized on your mobile device ?
Did you check that the ActiveSync/WMDC options "mail" was selected ? (not Outlook "E-mail")
Thanks.

i found out that in a german wm6 the folder gesendet / "send" is gesendete objekte / "send objects"

but, I had to create a normal "sent" box and also the "sent objects" / "Gesendete Objekte" and activate in birdiesync= Sync SMS "sent objects" / "Gesendete Objekte".
Then all mails will be in the "sent" box - not as checked in "sent objects".

OK. Your new account seems to have the correct configuration.
It's strange that in the SMS Thunderbird account you have 2 "Sent" folders (when we look at their icons). So here is what I suggest:

The goal is to now synchronize your SMS with a new SMS account:

As mentioned previously, do backup your SMS.

Create a new mail account called SMS2.
Create a "Sent" folder (with this exact name)
Restart Thunderbird: check that it was renamed to "Gesendet"

Disconnect your mobile device
Create additional folders InboxBackup and SendBackup on your mobile.
On the mobile, move your SMS from Inbox to InboxNew
On the mobile, move your SMS from Sent to SentNew
Synchronize your mobile device (that should remove your SMS from Thunderbird since they were moved in mobile folders not synchronized)

Disconnect your mobile device
Delete your previous SMS mail account in Thunderbird
Rename your new SMS2 mail account to "SMS"
Check that its folders are properly selected in BirdieSync options (Inbox and Sent)
On the mobile, move your SMS from InboxNew to Inbox
On the mobile, move your SMS from SentNew to Sent
Synchronize again your SMS.
Check now that the SMS are properly synchronized (they should have been transfered in Thunderbird)

-> this is correct - it renames automatically sent to Gesendet

I found out, that at the first sync of the sms inbox, the date and time of every sms is correct transfaired into my thunderbird SMS account.
But during the next sync (reconnect pda) all sms dates are changed to the actual sync time (now for example 11.24 pm)

you can try it if you have for example 20 "old" sms from last week at your pda inbox and sync it - after a second sync all times are wrong. only new incoming sms has it's new date

I have some problems during syncing SMS.
After I created SMS account in TB, I had only Inbox and Deleted Items. I created some folders, but TB didn't recognized it's like special ones (because I put names in polish - my fault!) Because of this, BirdieSync created this folders also on my mobile. Now I don't know how to delete this folders... I did this in TB, but they still are on my mobile :/

it worked but I find it impossible to avoid the sms' to show up in the smart folders, clogging them
the filter works, but only for the current session, you have to reapply it every time...
suggestions?
